The use of nanoparticles to enhance oil recovery

“…The effects arising from the use of these substances are associated with a change in the wettability of rocks, a decrease in the viscosity of oil, a decrease in interfacial tension, a decrease in the coefficient of mobility and a change in permeability. Another example of the use of nanoparticles (in order to increase the efficiency of oil production) as an additive during operation was presented by the University of Alaska, where some researchers identified important characteristics guaranteed by the use of metal nanoparticles dispersed in supercritical CO 2 , responsible for reducing the viscosity of heavy oil with a subsequent increase in extraction efficiency [12][13][14][15][16]. The figure (Figure 1) shows a scheme of chemical flooding with the use of nano-containing solutions to increase oil recovery.…”
